` INKING MECHANISIVI FOR PRINTING-PRESSES.

Patented May 31, 1921.

Application Ied April 26, 1919, Serial No. 294,002. Renewed April 16, 1921. Serial No. 461,918.

To all whom t may concern:

Be it known that I, ROBERT S. PHILIP, a citizen of the United States, residing in the city of Los Angeles, county of Los Angeles, and State of California, have invented certain new and useful Improvements in Inking Mechanism for Printing-Presses, of which the following is a specification.

- My invention relates to inking mechanism for printing presses, and the primary object thereof is to provide an improved form of distributing means by means of which the ink is delivered in a uniform amount from the inking fountain to the form and in order to carry out the said object, I have provided a new and novel arrangement of old elements, together with certain new elements 0f my invention, whereby greater speed of the press may be obtained than with other well known types of mechanism.

IA further object is toN provide in lieu of the generally used disk, *to-which the ink is transferred from the inking fountain or other ink holding means to the form rollers, a cylinder of large diameter for receiving the supply of ink and from the ink is intermittently transferred to the said form rollers.

Another object is to provide a unit mechanism comprising a suitable frame with a cylinder, distributing rollers, a vibrator roller, and an vink fountain mounted thereon for coperation and attachable to all types of small presses to which a mechanism of this character is adaptable.

AA still furtherv object is to provide independent means for operating the distributing ,rollers and cylinder and supported on the `same frame which holds said rollers, thus providing a separately controlled source of power for the inking mechanism, whereby l .the inking unit maybe readily attached to Ymany common types of presses without alteration of the press or modification of the inking mechanism to suit varying conditions. Other objects will appear as the description progresses. i

I-Iaving in-mind the above and other objects, I have shown 'in the accompanying drawing, forming apart of this application, a novel arrangement'and form of parts combined to provide one practical embodiment of my invention, which I will describe in detail.

Referring to the said drawings, in which similar characters of reference are employed throughout the several views for indicating the same and like parts,

Figure l is a plan of my improved mechamsm,

Fig. 2 is a side elevation of the same,

Fig. 8 is a rear elevation of the same.

Fig. a is a longitudinal section of the same showing the relative positions and size of the various rollers and elements.

Only a portion of a wellfknown type of printing press is shown in the drawings for the purpose of illustrating the manner in which my device may be attached to the frame of the press, the portion so shown being known as the bed of the press, as indicated at l, and comprising a pair of oppositely positioned members of like character, pivoted to the base of the main frame. Members l, l, are adapted to carry the form (not shown) on the front side thereof and are connected near their upper extremities by means of a transverse shaft 2, carried in bearings 3, 3, connecting rods 4, 4, being ec centrically connected with the ends 5, 5, of said shaft and being adapted to connect at their other ends with cranks or eccentrics for moving the back forward and backward during the printing operation.

A form roller bearer 6, is provided on the outer side of each of the back members l, l, and is pivoted on the ends of shaft 2, said members being connected at the rear by means of a transverse rail 7. Members 6, 6, are adapted to be oscillated about their common axis and carry` on their forward ends a triplet of form rollers f, f, 7", which are yield: ably supported thereon and are adapted to be moved over the runner' faces 8, 8, of the back members l, l, in the usual manner, said faces being so arranged as to move the said form rollers backward and forward over the form and in contact with the inking rollers to be hereinafter described, alternately.

My mechanism includes a pair of like frame members 9, 9, provided with teeth 1U,

. substantially largey diameter,

ends of said runner faces are substantially horizontal.

Frame members 9, 9, are spacedapart and connected by means of square rods 13, 13, which are held thereon by means of nuts 14, 14, onthe outside of said members. Between the members 9, 9, and spaced therefrom at the ends, I provide a metal cylinder C, of which is revolubly held on a transverse shaft 15, carried in bearings 16, 16, in frame members 9, 9, and the runner faces of frames 9, 9, at the rear ends are slightly lower than the periphery of said cylinder, as shown.

An electric motor M is supported on a plate 17, which is suspended from the trans verse spacer rods 13, 13and attached thereto and motion is adapted to be communicated to the cylinder C from motor M by means of a train of speed reduction gears including a pinion 18, on the motor shaft 19, an idler set of gears 20 and 21 of different size on a stud orshaft 22, attached to one end of the frame members 9, an idler 23 on a stud or shaft 25 also attached to frame 9,

and a relatively larger gear 26 carried on thecylinder shaft 15. Thus pinion 18 drives gears 20 and 21, gear 21 drives gear 23, and gear 23 drives the cylinder gear 26, and the cylinder C is rotated continuously in a clockwise direction during the operation of the press.,

A pair of composition distribution rollers CZ and d are carried on shafts 27 and 28, respectively, between the frame members 9, 9, and the ends of said shafts are looisely held in inclined slots 29 and y30, formed in the 'rear edges of said frame members, so that the rollers al and CZ will contact loosely with the large cylinder C. The slots 30, 30, in frame members 9, 9, are so disposedras to also vhold the flattened ends 31, 31, of a transverse screw 32, having right and left intersecting threads thereon and a vibrator roller V, is supported on said screwV so as to Y contact with both of the distributing rollers CZ and d', and is rotated thereby, thus caus- 'ing a longitudinal movement of the roller on the screw, as in other types of vibrator rollers, for providing a uniform distribution of the inlr on rollers CZ and d.

The ink fountain F comprises a housing 33 having feet 34, 34,*thereon adapted to be attached to lugs 35, 35, formed on the rear sides of the frames 9, 9, and a metal roller 1, which is carried in separable bearings 36, 36, at the ends of said housing. Fountain F has the usual thin metallic contact plate 37 in the bottoni thereof, which is adapted to be pressed against the periphery of ink roller z', by means of a plurality of thumb screws, 39, 39, etc., for regulating the quantity of ink delivered from the ink roller i to the other rollers.

Intermediate of ink roller z', and the vibrator roller V, I provide a ductor roller D, of composition material, which is pivotally mounted on arms 40, 40, at the 'ends and is adapted to intermittently contact with the roller i and roller o for delivering a quan# tity of the ink vto the distributing rollers. Arms 40 and 40 are pivoted on a transverse rod 41 attached at VAthe ends to the frame members`9, 9.

The inlring roller z, is operated in the usual manner by means of a ratchet 41, carbe actuated by and at each oscillation of the form roller bearer members, 6, '6. VThe ductor roller D is oscillated between the rollers z' and V, by means ofa'n extension V45, on arm 40, projecting into the path of member 7 of the form roller bearer 6, and is adapted to be engaged thereby at each o aeration for engaging rollers D and V. xtension 45 may have a weight 46 thereon for restoring roller D to contact with roller z' after each operation.
